A particle of mass 1.3 kg is sliding down a frictionless slope inclined at 30º to the horizontal.The acceleration of the particle down the slope is A)1.3 m/s² B)9.8 m/s² C)0.5 m/s² D)8.5 m/s² E)4.9 m/s²

Question

Quizplus · Accepted Answer

The acceleration down the slope can be found using the formula:
a = g*sin(θ)
where g is the acceleration due to gravity and θ is the angle of the slope.
Substituting the values, we get:
a = 9.8 m/s² * sin(30º)
a = 4.9 m/s²
Therefore, the correct choice is E)4.9 m/s².
